FILLER.

, SPECIFICATION forming part of Letters Patent No. 515,884, dated March 6, 1894.

Application filed April 20, 1893.

Toa/ZZ whom t may concern:

Be it known thatI, HUGO SCHNEIDER, a subject of the Emperor of Germany, and a resident of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Fillers, of which the following, with the accompanying drawings, is a specification. v

My invention relates to fillers used in llin g tanks, barrels, bottles, and other closed ves-V sels with any kind of liquids.

The obj ect of my invention is an apparatus which, without the use of ioats, will automatically close a valve in the iller to shut olii the iiow of the liquid into ,the vessel being filled when the vessel shall have been filled to a desired degree. A

My invention consists in a diaphragm operated by air pressure, and also tothe construction and the combination of parts substantially as illustrated in the drawings, described herein, and defined in the claims.

In the drawings froming part of this specification, Figure 1 is a central vertical section of my improved filler. Fig. 2 is a front elevation of my improved filler. Fig. 3 is an enlarged cross-section through the diaphragm chamber, of my improved filler, and Fig. -i`

is an enlarged end view of the air-port way from the air-chamber to the diaphragm.

In the diierent figures of the drawings, 1 represents a broken section of ay barrel, or other vessel, being 'dl1ed, through the bunghole, 2, and through which passes the ller.

3 is an outer wall forming the cylindrical portion of the filler, and constitutes that part which enters the bung-hole, and to which my valve-closing device is attached on its side, and which carries the valve and iilling pipe at its top.

4: are lugs vent the filler from passing too far into the vessel being filled. Near thelower end of the cylinder 3 is a wall 5 which closes the cylinder and leaves what, for convenience,I term an airchamber, 6, in the bottom of the cylinder 3. Immediately above the wall 5, are lat- 7, through the cylinder. From the air chamber 6, vertically along one side of the cylinder 3, is an air-passage 8, which leads to the diaphragm hereinafter described. `The upper end of the cylinder 3, at 8', is enformed on the cylinder 3 to pre-y ssen no. 471.096. or@ man larged, ask illustrated, for carrying the closingvalve. Inside of the enlarged portion 3 of the ller are guides 9 which direct the vertical travel of the closing-valve 10. The top end of the filler is closed with a screw cap 11, through which passes vertically a rod 12 which is attached to the closing-valve 10, as illustrated.

13 is a packing arrangement of the usual construction, for making an air-tight connection around the rod 12 which operates the valve 10. A coil 'spring 14 is interposed be-u tween the top of the valve 10 andthe bottom of the screw-cap 11.

15 is a nipple opening into the filler, and provides a means of attachment for a hose through which the liquid is conducted through lthe ller into the vessel to be filled. The conducting hose is secured to the nipple 15 by any known means. To the top of the rod 12 is pivoted a link 16 by means of a screw 17, as illustrated. Above the lugs 4, upon one side of lthe cylinder 3, is formed a nipple 18. A cup 19, having a shank 20 is attached to the nipple 18as illustrated. Through the .shank 2O is an opening 2l, which coincides tion thereof. A plate 22 closes the cup 19, said plate 22 being secured to the cup 19 by means of screws or bolts 23, which pass through the plate 22 into the annular flange 19 that is formed around the top of the cup 19. On the under side of the plate 22 there mouth of the cup, making an air-tightcon# nection therewith. The space 25, between chamber, which I, for convenience, designate 1a diaphragm chamber. A diaphragm, 26, vdivides the diaphragm chamber 25. The diaphragm 26 is a circular disk formed of rubbottom edge of the flange 24 andthe bottom connection. The diaphragm 26 is provided with a metal backing piece 27, which is secured to the diaphragm 26 by means Iof a screw 28 which passes through the diaphragm 26 at its center, and screws into the backing l.The sides of the head of the screw 2S are cut is an angular flange 2t which lits within the n the cup 19 and the closing plate 22 forms a" of the cup 19, in order to make an air-tight piece 27, as illustrated in section in Fig-L1;

-with the air passage S, and forms a continuaber, or of other flexible material. The outer A edge of the diaphragm is held between ther IOC away as seen at 28' to form air port-ways from ance. Upon the backing plate 27 is formed' a lug 3l to which is pivoted alink 32. Upon the closing plate 22 is attached a bracket 33 to which is pivoted a bell crank 34. One end of the bell crank is pivoted to the outer end of the link 32, and to the opposite end of the bell crank 34 is pivoted a link 35, having the bent arm 35 which is pivotally connected with the arm 36. The arm 36 is integral with the arm 37, the arms 36 and 37 forming a bell-lever. Near the outer end of the arm 37 is formed a lip 37', whose function is hereinafter described. A rocking arm 38 is pivoted to the side of that part ot' the filler marked 3 by means of the pivot 39. The link 16 has its lower end pivoted to the upper end of the rocking arm 38. A trigger, 40, enters the lower end of the rocking arm 38, and is made adjustable vertically therein by any well known means. The adjustment of the trigscrew, or otherwise.

ger 40 may be made by means of screwing the trigger into the arm 38, or by lneans of a set As so many Ways will suggest themselves to mechanics, the adjustment of the trigger 40 in the arm 38 is not illustrated.

Instead of the diaphragm 26, the backing plate 27 maybe made to serve the purpose of a valve, the valve being provided with a cup leather or rubber back; but as the movement of the diaphragm is slight, the construction illustrated is preferable in view of the fact that it is simpler and is more susceptive to air pressure than would be a cup valve. The construction illustrated requires a Iiexible diaphragm 26, as previously described.

I have now fully described the construction of my improved filler. From the drawings and the description given, its operation will be readily understood.

In use, the filler is first placed in the bunghole of the vessel to be filled, as illustrated by Figs. 1 and 2. The trigger 40 is then pulled down so that its point is engaged and held by the lip 37 that .is formed on the arm 37. When the trigger 40 is pulled down and thus engages, the valve 10 in the valve case 3 is raised through the link 16 which connects the upper end of the arm 38 on the valve stem 12. So long as the trigger 40 is in engagement with the lip 37'of the arm 37, the valve 10 is raised against the resistance of the spring 14 and yheld open that any kind of fluid or liquid will freely pass from the connecting hose through the nipple 15 down through the cylinder 3 and out through the lateral openings 7 into the vessel 1. As the vessel is`filled,the air passes out of the bring around the filler cylinder until the liquid in the vessel comes up to and closes the open end of the air chamber 6. As the air in the chamber 6 and in the'passage way 8 is forced up by the rise of the iiuid in the vessel 1, the diaphragm 26 is sprung out, carrying with it the backing plate 27; the outward throwing of the link 32 raises the inner end of the bell crank 34, thus pulling to the right the upper end of the arm 36, which depresses the-outer end of the arm 37 andlets the end of the trigger 4Q free of engagement with the lip 37'. As the trip is freed, as described, the spring 14 in the valve head 3 forces the valve 10 upon its seat 10' aud closes the opening through the filler. Through the plate 22, which closes the cup 19, I make one or more openings 41 to allow the diaphragm to be moved forward without air resistance within the chamber.

It will be seen that my air operated diaphragm dispenses with the use of all floats, and avoids the uncertainty of operation of some iioats which arises from the nicety required in their construction. As the diaphragm is under spring resistance by means of the coil spring 30, and as the resistance of said coil spring 30 is regulated by means of the screw 29, the filler may be adjusted to close the valve l0 at any point desired after thevessel 1 shall have been filled up to the air chamber 6. The greater the resistance of the spring 30, the higher up the liquid will have to come upon the lower end of the filler in order to get the requisite air pressure from the air chamber 6 through the air passage way 8 to operate the diaphragm under its spring resistance.

My invention may take on various modifications in detail of construction, and Ido not, therefore, limit myself to the construction illustrated and described.
